Investigating the Effect of Use of Vegetable Oils in Lubricants

This study targeted at determining the effect of use of vegetable oils in lubricants. For this purpose some physical parameters (viscosity, viscosity index, pour point, flash point, density, color and total acid number tests) of canola, soy, olive, corn, hazelnut and castor oil were investigated. The same tests were made for ‘Heavy’, ‘Light’ and ‘Bright Stock’ base oils and the results were compared. Then physical properties of commercial hydrolic system lubricants were investigated and in order for to compare the results of both studies additives in the formulations were replaced with canola and castor oil. ASTM methods were used in the tests. While canola oil has provided positive results with respect to physical properties (viscosity, viscosity index and flash point) as additive, all other vegetable oils used except for castor oil gave positive results with respect to their physical properties in their use as base oils.
